I also always buy the phone that brings most profits. I do this with cars too. That's why I am driving Toyota Camry.
I'm not quite sure if you're being sarcastic or not...? For two reasons, first, the Camry is not the most profitable car - its actually 12th. Secondly, just because something is more profitable, does not mean it is better. In fact, one could argue the direct opposite - in that because it costs less to make versus another similarly priced product, it does not have all the same features or materials on par as the similarly priced product that costs more to make.
